Question

write displacement and double displacement reaction write equation of reaction
​

Answer 1

Answer:

2KI + Cl2 → 2KCl + I2 is a displacement reaction. CuSO4 + Zn → ZnSO4 + Cu is also a displacement reaction. Examples: Na2SO4 + BaCl2 → BaSO4 + 2NaCl is a double displacement reaction.

Answer 2

Answer:

Double displacement reaction

In a displacement reaction, a more reactive element replaces a less reactive element from a compound. In a double displacement reaction, two atoms or a group of atoms switch places to form new compounds. In a displacement reaction, one displacement takes place

A single-displacement reaction, is a chemical reaction in which one (or more) element(s) replaces an/other element(s) in a compound. It can be represented generically as: A + B-C → A-C + B. This will most often occur if A is more reactive than B, thus giving a more stable product.
